With a .63 under-seat box I'd be surprised if a sub like that is going to have the necessary mounting depth it needs.
You'll probably need to look for a shallow. If not an actual "shallow" sub, then one with a mounting depth 5" or less.
I put an MB Quart 12" in for a friend under an F150 back seat. Box claimed to be 5.5", sub was 5.25" but didn't quite fit. Had to make a 1/4" spacer for the front of the box. The sub has not disappointed.
Dayton has a shallow, all the mainstream brands have shallows. There are a few other options that aren't specifically "shallow" but might fit.
Figure out what depth you have to work with first and be aware of mounting depths.
